The present invention relates to an overturn preventing device.
Patent Document 1 discloses a conventional overturn preventing device. This overturn preventing device is mounted between a top surface of a piece of furniture installed on a floor and a ceiling. The overturn preventing device includes a support pillar with a built-in spring and setting members attached to both ends of the support pillar respectively. Each setting member includes a disk-shaped setting part body and a columnar shaft vertically extending from a center of one side surface of the setting part body. The shafts of the setting members are inserted into both ends of the support pillar respectively, and at least one of the shafts is disposed to be axially movable forward and backward. The spring applies an elastic force to each setting member which is movable forward and backward in a lengthwise direction of the overturn preventing device. While the spring is slightly compressed, the setting part body of one setting member is caused to abut against the top surface of the furniture and the setting part body of the other setting member is caused to abut against the ceiling. Thus, the overturn preventing device is mounted between the top surface of the furniture and the ceiling with an axis line extending in a vertical direction, thereby preventing the furniture from being overturned due to quakes of earthquake or the like.
Patent Document 1: Japanese Utility Model Registration No. 3028334
However, when the furniture on which the overturn preventing device of Patent Document 1 is mounted is tilted by quakes of earthquake or the like, a force of the overturn preventing device preventing overturn of the furniture concentrates on a part of the top surface of the furniture or the ceiling which part the setting part body of the setting member abuts against. Accordingly, when the overturn preventing device is mounted while the setting part body abuts against a part having low strength of the top surface of the furniture or the ceiling, there is a possibility that the top surface of the furniture or the ceiling would be broken when the furniture is tilted by quakes of earthquake or the like. In this case, the overturn preventing device cannot successfully apply a force to the furniture, with the result that the furniture cannot be prevented from being overturned.
The present invention was made in view of the above-described circumstances in the conventional art and provides an overturn preventing device which can successfully prevent articles from being overturned.
An overturn preventing device according to the present invention includes a damper mounted between an article and a ceiling or the like, and a setting member connected to at least one of two ends of the damper and having a plurality of setting part bodies which is spread when the overturn preventing device is mounted between the article and the ceiling or the like. The setting member assumes such a shape as to extend in one direction when the setting part bodies are unspread.
In the overturn preventing device according to the present invention, the setting member may have a connecting part rotatably connected to the one end of the damper. In the overturn preventing device according to the present invention, furthermore, the setting part bodies may have fitting portions which are fitted with each other when spread, so that abutting surfaces are coplanar.
First to third embodiments of the overturn preventing devices of the present invention will be described with reference to the drawings.
First Embodiment
At least one overturn preventing device 10 of the first embodiment is mounted between a top surface 1U of a piece of furniture 1 installed on a floor surface (not shown) and a ceiling C while a rear surface 1B of the furniture 1 is opposed to a wall surface W extending in a vertical direction from the floor surface, as shown in
The overturn preventing device 10 includes a damper 20 mounted between the top surface 1U of the furniture 1 and the ceiling C and two setting members 30 connected to both ends of the damper 20 and mounted on the top surface 1U of the furniture 1 and the ceiling C, respectively.
The damper 20 has a cylinder 21, a piston (not shown), a rod 23 and a rod guide (not shown). The cylinder 21 has a bottomed cylindrical shape. The rod guide closes an opening of the cylinder 21. The piston is slidably inserted into the cylinder 21. The rod 23 has a proximal end connected to the piston and extends through the rod guide. The rod 23 has a distal end side protruding out of the cylinder 21. The cylinder 21 is filled with operating oil and a gas.
The damper 20 is a compression damper in which a damping force generated during an extending operation is smaller than a damping force generated during a compressing operation. The extending operation of the damper 20 refers to an operation which increases an amount of protrusion of the rod 23 out of the cylinder 21 and an entire length of the damper 20. On the other hand, the compressing operation of the damper 20 refers to an operation which reduces an amount of protrusion of the rod 23 out of the cylinder 21 and the entire length of the damper 20.
A mechanism that the damper 20 generates a damping force will be described. Since the mechanism has a known structure, diagrammatic representation is eliminated. The cylinder 21 has an interior divided by the piston into a rod side pressure chamber in which the proximal end of the rod 23 is housed and a counter-rod side pressure chamber. The piston is formed with an orifice which is a throttle valve communicating between both pressure chambers. The orifice functions as a damping force generator which applies resistance to a flow of the operating oil between the rod side pressure chamber and the counter-rod side pressure chamber with the extending/compressing operation of the damper 20. Furthermore, the piston is formed with a communication path communicating via a check valve with both pressure chambers. The check valve allows the operating oil to flow from the rod side pressure chamber to the counter-rod side pressure chamber and blocks reverse flow of the operating oil. Accordingly, the damper 20 has two flow paths of the operating oil from the rod side pressure chamber to the counter-rod side pressure chamber during the extending operation, that is, one flow path including the orifice and the other flow path including the communication path. On the other hand, the damper 20 has only one flow path of the operating oil from the counter-rod side pressure chamber to the rod side pressure chamber through the orifice during the compressing operation. Accordingly, the damping force generated by the damper 20 during the extending operation is smaller than the damping force generated by the damper 20 during the compressing operation.
Each setting member 30 has a first setting part body 31, a second setting part body 32 and a rotating shaft 33 to which the first and second setting part bodies 31 and 32 are rotatably connected, as shown in
The first flat plate 34 is formed with a groove 31A which is located in a longitudinal middle of the reverse side thereof and serves as a fitting portion, as shown in
The connecting part 35 has a connecting part body 35A and a shaft member 35B as shown in
The second setting part body 32 includes a second flat plate 36 having an identical outer configuration with the first flat plate 34 of the first setting part body 31, as shown in
The rotating shaft 33 has two ends connected to central parts of grooves 31A and 32A formed in the first and second flat plates 34 and 36 respectively, as shown in
When each setting member 30 is mounted to the top surface 1U of the furnace 1 or the ceiling C, the first and second setting part bodies 31 and 32 are spread so as to be located to be perpendicular to each other, as shown in
Furthermore, the first and second setting part bodies 31 and 32 can be caused to overlap without being spread, into such a shape as to extend in one direction, as shown in
The overturn preventing device 10 of the first embodiment includes the damper 20 mounted between the top surface 1U of the furniture 1 and the ceiling C and the setting members 30 connected to the ends of the damper 20 respectively. Each setting member 30 has the first and second setting part bodies 31 and 32. When the overturn preventing device 10 is mounted between the top surface 1U of the furniture 1 and the ceiling C, the first and second setting part bodies 31 and 32 are spread so as to be perpendicular to each other. Furthermore, the setting members 30 extend in one direction when the first and second setting part bodies 31 and 32 are not spread.
When the furniture 1 is tilted forward by quakes of earthquake or the like, the tilt of the furniture 1 is suppressed by the damping force of the damper 20 with the result that the furniture 1 is prevented from being overturned by the overturn preventing device 10 mounted between the top surface 1U of the furniture 1 and the ceiling C. When the overturn preventing device 10 is mounted between the top surface 1U of the furniture 1 and the ceiling C, the first and second setting part bodies 31 and 32 are spread so as to be located to be perpendicular to each other, so that the first and second abutting surfaces 31B and 32B extend in respective directions perpendicular to each other thereby to be caused to abut against the top surface 1U of the furniture 1 and the ceiling C. This increases an abutment area of each setting member 30 against the top surface 1U of the furniture 1 and the ceiling C. As a result, the overturn preventing device 10 can disperse the damping force of the damper 20 applied to the top surface 1U of the furniture 1 and the ceiling C when the furniture 1 is tilted forward. In other words, the damping force of the damper 20 applied to the top surface 1U of the furniture 1 and the ceiling C can cover a wide range and an applied force per unit area can be rendered smaller. Accordingly, the overturn preventing device 10 can be mounted to any portions of the top surface 1U of the furniture 1 and the ceiling C but not only to higher strength portions of the top surface 1U of the furniture 1 and the ceiling C, with the result that the furniture 1 can be prevented from being overturned due to quakes of earthquake or the like.
Accordingly, the overturn preventing device 10 of the first embodiment can successfully prevent the furniture 1 from being overturned.
Furthermore, the first and second setting part bodies 31 and 32 remain unspread until the overturn preventing device 10 is mounted between the top surface 1U of the furniture 1 and the ceiling C, so that the first and second setting part bodies 31 and 32 extend in one direction. More specifically, the setting members 30 are caused to extend in one direction and furthermore to be located so that the extension directions of the setting members 30 are parallel to the axis line of the damper 20. As a result, handling of the overturn preventing device 10, such as carrying, can be rendered easier until the overturn preventing device 10 is mounted between the top surface 1U of the furniture 1 and the ceiling C.
Furthermore, the first and second setting part bodies 31 and 32 have the respective grooves 31A and 32A serving as the fitting portions which cause the first and second abutting surfaces 31B and 32B to be coplanar. Accordingly, since this increases an abutment area of the setting members 30 against the top surface 1U of the furniture 1 and the ceiling C, the overturn preventing device 10 can disperse the damping force which the damper 20 applies to the top surface 1U of the furniture 1 and the ceiling C when the furniture 1 is tilted by quakes of earthquake or the like. Consequently, the overturn preventing device 10 can be mounted on any part of the top surface 1U of the furniture 1 and any part of the ceiling C without limitation to higher strength portions in order to prevent the article from being overturned by the quakes of earthquake or the like.
Second Embodiment
An overturn preventing device 110 of a second embodiment differs from that of the first embodiment in the configuration of setting member 130 as shown in
The setting member 130 of the overturn preventing device 110 includes a first setting part body 131 and two second setting part bodies 132. The first setting part body 131 includes a first flat plate 134 having a rectangle shape extending in one direction (a right-left direction in
The connecting part 35 has a connecting part body 35A and a shaft member 35B. The connecting part body 35A protrudes from the longitudinal middle obverse side of the first flat plate 134. The shaft member 35B is cylindrical in shape and extends through a distal end of the connecting part body 35A in parallel to the longitudinal direction of the first flat plate 134. The damper 20 has both ends (a distal end of the rod 23 and a proximal end of the cylinder 21) provided with a pair of damper side connecting parts 21A and 23A which interpose the connecting part body 35A respectively. The paired damper side connecting parts 21A or 23A are provided with through-holes respectively through which both ends of the shaft member 35B extend in a retained state. Consequently, the damper 20 is connected to be rotatable in a direction perpendicular to the longitudinal direction of the first flat plate 134 about the shaft member 35B of the connecting part 35.
The second setting part bodies 132 have respective thicknesses equal to that of the first flat plate 134 and include respective second flat plates 136 having a rectangle shape and extending in one direction. Each second flat plate 136 has longitudinal sides one of which is formed with a semi-cylindrical recess 137 fitted with the shaft 133 of each first flat plate 134. The second flat plates 136 are rotatable about the shafts 133 relative to the first flat plates 134 respectively. As a result, the second setting part bodies 132 are rotatable between a spread state (see
When the setting members 130 are mounted between the top surface 1U of the furniture 1 and the ceiling C, the first and second setting part bodies 131 and 132 are spread with the result that the first and second abutting surfaces can be caused to abut against the top surface 1U of the furniture 1 or the ceiling C as shown in
The overturn preventing device 110 of the second embodiment is also provided with the damper 20 mounted between the top surface 1U of the furniture 1 and the ceiling C and the setting members 130 connected to both ends of the damper 20 respectively. Each setting member 130 has the first and second setting part bodies 131 and 132. The first and second setting part bodies 131 and 132 of each setting member 130 are spread into the T-shape when the overturn preventing device 110 is mounted between the top surface 1U of the furniture 1 and the ceiling C. Furthermore, each setting member 130 extends in one direction when the first and second setting part bodies 131 and 132 are unspread.
When the furniture 1 is tilted forward by quakes of earthquake or the like, the tilt of the furniture 1 is suppressed by the damping force of the damper 20 with the result that the furniture 1 is prevented from being overturned by the overturn preventing device 110 mounted between the top surface 1U of the furniture 1 and the ceiling C. When the overturn preventing device 110 is mounted between the top surface 1U of the furniture 1 and the ceiling C, the first and second setting part bodies 131 and 132 are spread into the T-shape, so that the first and second abutting surfaces extend into the T-shape and are caused to abut against the top surface 1U of the furniture 1 and the ceiling C respectively. As a result, the overturn preventing device 110 can disperse the damping force of the damper 20 applied to the top surface 1U of the furniture 1 and the ceiling C when the furniture 1 is tilted forward. More specifically, the damping force of damper 20 applied to the top surface 1U of the furniture 1 and the ceiling C can cover a wide range and an applied force per unit area can be rendered smaller. Accordingly, the overturn preventing device 110 can be mounted to any portions of the top surface 1U of the furniture 1 and the ceiling C but not only to higher strength portions of the top surface 1U of the furniture 1 and the ceiling C, with the result that the furniture 1 can be prevented from being overturned due to quakes of earthquake or the like.
Accordingly, the overturn preventing device 110 of the second embodiment can successfully prevent the furniture 1 from being overturned.
Furthermore, the first and second setting part bodies 131 and 132 remain unspread until the overturn preventing device 110 is mounted between the top surface 1U of the furniture 1 and the ceiling C, so that the first and second setting part bodies 131 and 132 extend in one direction. As a result, handling of the overturn preventing device 110, such as carrying, can be rendered easier until the overturn preventing device 110 is mounted between the top surface 1U of the furniture 1 and the ceiling C.
Third Embodiment
An overturn preventing device 210 of a third embodiment differs from those of the first and second embodiments in the configuration of setting member 230 as shown in
The setting member 230 of the overturn preventing device 210 includes a first setting part body 231, two second setting part bodies 232 and rotating members 233 rotatably connecting the first setting part body 231 and the respective second setting part bodies 232 between the spread state and the unspread state. The first setting part body 231 includes a first flat plate 234 having a rectangle shape and extending in one direction (a depthwise direction in
The connecting part 35 has a connecting part body 35A and a shaft member 35B. The connecting part body 35A protrudes from the lateral middle obverse side (the right-left direction in
The second setting part bodies 232 have respective thicknesses equal to that of the first flat plate 234 and include respective second flat plates 236 having a rectangle shape and extending in one direction (the depthwise direction in
Each rotating member 233 is formed into a tape-shape and attached to an end surface of the longitudinal side concave portion 234B of the first flat plate 234 and the longitudinal side convex portion 236A of the longitudinal side of the second flat plate 236. Each rotating member 233 is foldable at a boundary between the first and second flat plates 234 and 236.
When the setting members 230 are mounted between the top surface 1U of the furniture 1 and the ceiling C, the first and second setting part bodies 231 and 232 are spread with the result that the first and second abutting surfaces 231B and 232B can be caused to abut against the top surface 1U of the furniture 1 or the ceiling C, as shown in
The overturn preventing device 210 of the third embodiment also includes the damper 20 mounted between the top surface 1U of the furniture 1 and the ceiling C, and the setting members 230 connected to both ends of the damper 20 respectively. Each setting member 230 has the first setting part body 231 and the second setting part bodies 232. When the overturn preventing device 230 is mounted between the top surface 1U of the furniture 1 and the ceiling C, the first and second setting part bodies 231 and 232 of each setting member 230 are spread. Furthermore, each setting member 230 assumes such a shape as to extend in one direction when remaining unspread.
When the furniture 1 is tilted forward by quakes of earthquake or the like, the tilt of the furniture 1 is suppressed by the damping force of the damper 20 with the result that the furniture 1 is prevented from being overturned by the overturn preventing device 210 mounted between the top surface 1U of the furniture 1 and the ceiling C. When the overturn preventing device 210 is mounted between the top surface 1U of the furniture 1 and the ceiling C, the first and second setting part bodies 231 and 232 are spread and the first and second abutting surfaces 231B and 232B are caused to abut against the top surface 1U of the furniture 1 and the ceiling C. As a result, the overturn preventing device 210 can disperse the damping force of the damper 20 applied to the top surface 1U of the furniture 1 and the ceiling C when the furniture 1 is tilted forward. In other words, the damping force of damper 20 applied to the top surface 1U of the furniture 1 and the ceiling C can cover a wide range and an applied force per unit area can be rendered smaller. Accordingly, the overturn preventing device 210 can be mounted to any portions of the top surface 1U of the furniture 1 and the ceiling C but not only to higher strength portions of the top surface 1U of the furniture 1 and the ceiling C, with the result that the furniture 1 can be prevented from being overturned due to quakes of earthquake or the like.
Accordingly, the overturn preventing device 210 of the third embodiment can successfully prevent the furniture 1 from being overturned.
Furthermore, the first and second setting part bodies 231 and 232 remain unspread until the overturn preventing device 210 is mounted between the top surface 1U of the furniture 1 and the ceiling C, so that the first and second setting part bodies 231 and 232 extend in one direction. In other words, each setting member 230 assumes such a shape as to extend in one direction and furthermore, each setting member 230 is located so that the extension direction thereof and the axis line of the damper 20 are parallel to each other. As a result, handling of the overturn preventing device 210, such as carrying, can be rendered easier until the overturn preventing device 210 is mounted between the top surface 1U of the furniture 1 and the ceiling C.
